4 Claims.

This invention relates to wheel mountings. More particularly the invention is concerned with means for securing a Wheel hub on a wheel box without finishing the mating parts of the wheel box and hub to insure their assembly.

In agricultural machines and the like, it is necessary many times to replace the wheels provided thereon. Ordinarily, the implement is provided with bearing-mounted wheel boxes which last the life of the implement. However, the wheels that are mounted on these Wheel boxes become worn with use and must be replaced. It has been somewhat of a problem to supply repair wheels for these implements that will always fit the wheel box. It has been necessary to finish the mating portions of the wheel box and Wheel hub to close dimensions so as to insure their fit.

It is, therefore, an important object of the present invention to provide an improved wheel mounting.

Another object of the present invention is to provide a wheel box and wheel hub construction which can be quickly and easily assembled.

Another object of the present invention is to provide a wheel mounting which does not require that the mating parts of the wheel box and wheel hub be finished to close dimensions.

According to the present invention, the implement is provided with bearing-mounted wheel boxes which consist of a radial flange and a conical portion having spaced longitudinal grooves. The hub of the wheel is provided with an opening that is somewhat larger than the outer diameter of the conical portion, so that the hub may be easily inserted over the conical portion. The wheel hub is bolted to the radial flange, and flat springs are inserted in the longitudinal grooves so as to carry the load on the wheel box. The springs also compensate for the difierence in diameters of the wheel box and wheel hub.

These and other objects and advantages of the present invention will be apparent to those skilled in the art after a consideration of the following detailed description of the preferred structural embodiment, taken in conjunction with the accompanying drawing.

In the drawing,

Figure 1 is an end view of the novel wheel hub and wheel box mounting;

Figure 2 is a sectional view taken along the line 2-2 of Figure 1; and,

Figure 3 is a perspective view of one of the springs which carry the load of the wheel on the wheel box.

Referring now to the drawing, it will be seen that the novel wheel mounting comprises a Wheel box I!) which consists of a conical portion I I, from one end of which extends a radial flange I2. The periphery I3 of the conical portion II tapers outwardly from the radial flange l2. The wheel box Ii] is journaled on an axle I I by means of roller bearings I5 which are held on the axle I4 by a nut Hi.

The wheel box I0 and the bearings I5 most generally last the life of the implement. A suitable lubrication means I'Ia is provided in the hub ll, by which the bearings I5 are lubricated.

The wheel hub II, in which an opening I8 is provided of a diameter greater than the outer diameter or periphery I3 of the conical portion I I, is inserted over the periphery l3. The opening I 8 is tapered so as to match the conical portion I I. The huh I! is provided with four equally spaced openings I8 that are arranged parallel to the axle I4. Alined openings 20 are provided in the radial flange I2. Bolts 2|, inserted in the openings I8 and 20, secure the hub I! to the radial flange I 2. It is to be noted that a considerable space is provided between the periphery I3 of the conical portion II and the diameter of the opening I8 in the wheel hub II. By this construction, the wheel hub may be quickly and easily mounted on the wheel box. If desired, the face of the radial flange I2 and the end of the wheel hub Il may be finished to insure even rotation of the Wheel.

The weight or load, however, cannot be carried on the bolts 2|. Therefore, a novel load-carrying means is provided, by which the load is carried directly on the periphery I3 of the wheel box Ill. The periphery I3 is provided with three equally spaced longitudinal grooves 22 into which a flat spring 23 is inserted. The'spring 23, shown in Figure 3, is provided with a plurality of raised portions 24 which extend from the base portions 25. After the hub I1 is bolted to the radial flange I2, the flat springs 23 are driven into the longitudinal grooves 22. The springs 23 are under compression and carry the load of the wheel on the conical portion I I. A cap 2i is secured to the end of the conical portion I l by machine screws 21 to retain the springs 3 n p The cap 26 also keeps dirt out of the bearings I5.

From the foregoing description it should be apparent that a novel wheel mounting has been provided by this arrangement of parts. Sufiicient space is provided between the wheel hub and the wheel box so that the wheel may be readily mounted thereon. The bolts secure the wheel hub to the wheel box, and the load is carried on the conical portion of the wheel box by means of springs which are inserted between the wheel box and wheel hub. The wheel box and wheel hub are easy and economical to manufacture, since the parts need not'be finished to close dimensions.

While only a preferred construction embodying the principles of the present invention has been herein chosen and described, it is to be unover the wheel box, bolt means securing the hub to the peripheral flange, and a plurality of leaf spring means inserted between the wheel box and the hub for carrying the load on said wheel box.

3. In a wheel mounting, an axle, a wheel box journaled for rotation on the axle, said wheel box having a conical portion at one end of which extends a radial flange, said conical portion having a plurality of longitudinal grooves, a wheel having a hub portion provided with an opening that is inserted over the conical portion of the derstood that the invention is not to be limited I to the specific details shown and described but that, in fact, widely diilerent means may be employed in the broader aspects of this invention.

What is claimed is:

1. In a wheel mounting, an axle, a wheel box journaled for rotation on the axle, said wheel box having a peripheral flange, a wheel having a hub portion provided with an opening that is inserted over the wheel box, means for securing the hub to the radial flange, and a plurality of leaf spring means inserted between the wheel box and the hub for carrying the load on said wheel box.

2. In a wheel mounting, an axle, a wheel box journaled for rotation on the axle, said wheel box having a radial flange, a wheel having a hub portion provided with an opening that is inserted wheel box, bolt means securing the hub to the peripheral flange, and a leaf spring inserted in each of said longitudinal grooves and adapted to contact the opening in the hub portion to carry I the load on said wheel box.

4. In a wheel mounting, an axle, a wheel box journaled for rotation on the axle, said wheel box having a conical portion at one end of which extends a radial flange, said conical portion having three spaced longitudinal grooves, a wheel having a hub portion provided with an opening that is inserted over the conical portion of the wheel box, bolt means securing the hub to the peripheral flange, and a leaf spring inserted in each of said longitudinal grooves and adapted to contact the opening in the hub portion to carry the load on said wheel box.
